Thanks! I would also be interested in your impressions of the relay/wire kit. They are about 2x the avg price of other relay kits claiming to use 12/14 g wire and Hella relays, but I thought they might be worth it if everything was pre sized to my w124 and had all the proper connectors, etc. Reading their site again led to the disclaimer that their kits were 'not model specific'. I am not quite ready to do this project, (doing speakers on the C230) so I haven't called them with questions. Your feedback would be welcome!
